Deadlands: Shadows in the West
This mysterious Fuel burns at an extremely high temperature. Only furnaces and forges built to accommodate the high temperatures can use Ghost Rock. One strange feature about his substance is that it produces an extremely loud noise when burned.
It has been documented recently that repeated exposure to this sound can have detrimental effects on the psyche of those able to hear it. Some describe it as a deafening roar. Other say it is the wailing of damned souls. Some claim that this dark eerie stone also has mystical properties.
